Zeros of Nonlinear Monotone Operators in Hilbert Space*
Rainald Schöneberg · Canadian Mathematical Bulletin · 1978
Around 1960, the Russian mathematician Kachurovski [1] introduced the notion of monotone operators in Hilbert spaces: Let E be a Hilbert space and X ⊂ E. An operator T:X→E is said to be monotone, iff .
